Warning
!
Failure to follow these instructions or to properly
install and maintain this equipment could result in
an explosion and/or fire causing property damage
and personal injury or death.
Fisher equipment must be installed, operated,
®
and maintained in accordance with federal, state,
and local codes and Fisher instructions. The
installation in most sates must also comply with
nFPa no. 54 and 58 standards.
Only personnel trained in the proper procedures,
codes, standards, and regulations of the
LP-gas industry should install and service
this equipment.
THINGS TO TELL THE GAS CUSTOMER:
1. Point out the regulator's vent to the customer (or vent
assembly or vent tube), and stress that this opening must
remain unobstructed at all times. Tell the customer to be
sure to check the vent opening after a freezing rain, sleet
storm, or snow to makes sure ice has not formed in the vent.
2. Show the customer to shutoff valve on the container. The
customer should close this valve immediately if gas is
smelled, appliance pilot lights fail to stay on or appear higher
than usual, or any other abnormal situation occurs.
3. Tell the customer to call your company to service the
regulator if the regulator vents gas or a leak develops in the
system. Only a qualified gas service person should
install or service the regulator.

Scope of Manual

This manual provides instructions and maintenance for the
following high pressure regulators: Types 64, 64KB, 64SR,
67CW, 67CH, 67CD, and 67CN regulators.

Description

The 64 and 67C Series direct-operated regulators (Figure 1) are
designed for high-pressure (pounds per square inch) service and can
be used on either vapor applications in LP-Gas, Natural Gas and Air
or liquid LP-Gas applications. Depending upon type, outlet pressure
ranges from 3 to 135 psig (0,21 to 9,3 bar). The Type 64SR can be
used as a First Stage LP-Gas regulator–reducing tank pressure to
10 psig (0,69 bar) for a Second Stage regulator. The Type 64KB
is the only regulator in this series suitable for anhydrous ammonia
(NH ) service. The regulators are normally painted red.
